alpha: move include/asm-alpha to arch/alpha/include/asm

2008-08-15T16:19:40Z

Sam Ravnborg did the build-test that the direct header file move works, I'm just committing it. This is a pure move: mkdir arch/alpha/include git mv include/asm-alpha arch/alpha/include/asm with no other changes.

generic: implement __fls on all 64-bit archs

2008-04-26T17:21:16Z

Implement __fls on all 64-bit archs: alpha has an implementation of fls64. Added __fls(x) = fls64(x) - 1. ia64 has fls, but not __fls. Added __fls based on code of fls. mips and powerpc have __ilog2, which is the same as __fls. Added __fls = __ilog2. parisc, s390, sh and sparc64: Include generic __fls. x86_64 already has __fls.

forbid asm/bitops.h direct inclusion

2007-10-19T18:53:41Z

forbid asm/bitops.h direct inclusion Because of compile errors that may occur after bit changes if asm/bitops.h is included directly without e.g. linux/kernel.h which includes linux/bitops.h, forbid direct inclusion of asm/bitops.h.

alpha: lock bitops

Alpha can avoid one mb when acquiring a lock with test_and_set_bit_lock. [bunk@kernel.org: alpha bitops.h must #include ] Signed-off-by: Nick Piggin Cc: Richard Henderson Cc: Ivan Kokshaysky Signed-off-by: Adrian Bunk Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

alpha: fix bitops

2007-10-18T21:37:29Z

Documentation/atomic_ops.txt defines these primitives must contain a memory barrier both before and after their memory operation. This is consistent with the atomic ops implementation on alpha.

bitops: introduce lock ops

2007-10-18T21:37:29Z

Introduce test_and_set_bit_lock / clear_bit_unlock bitops with lock semantics. Convert all architectures to use the generic implementation.

alpha: cleanup in bitops.h

2007-05-30T17:07:54Z

Remove 2 functions private to the alpha implemetation, in favor of similar functions in . Provide a more efficient version of the fls64 function for pre-ev67 alphas. Signed-off-by: Richard Henderson Signed-off-by: Linus Torvalds

Don't include linux/config.h from anywhere else in include/
